I have several dc items to plug in and don't want to have a whole bunch of lighter type sockets (bad design from inception) cluttering up the boat. Instead I want to run a line to a outlet box and have 4 outlets avail to plug in non lighter type plugs.

Do they make a plug/outlet for this?

I suppose I could just use regular 120v outlets but to avoid confusion, I'd like it different. Is there anything wrong with using a different plug like rca, bnc or coax 'f' connector? All of the lighter type cords I have seen are made with very small wire so it seems like almost any good 2 conductor connector would work. I chose the three above because I can easily fit all four outlets in a small space.

Thanks for the link Pelagic but I checked the site and they seem to have mostly just DIN (lighter plug) type connectors, which I'd like to avoid if possible.

As for the connectors ability to handle the load, I can speak from experience on only the coax cable. Cable is my business and I have seen old RG-6 temporary lines long forgotten that were carrying 90 volts for several hundred feet to power main amplifiers. I'm unsure about the exact amperage, but I can verify that its enough to knock a 180 lb guy squarely on his a$$.

Another example, I came across a guy one day up in a bucket truck using a 1/2" hammer drill using the RG-6 as an extension cord. He said his cord got cut one day and he had to makeshift it and later decided if it works, why not keep it that way as there is no shortage of cable on a cable truck incase he cut it again.

Nothing really but other factors steer me away from RG-6 like its stiffness which prevents clean looking wiring (look behind your entertainment center). Also cutting a din plug off a wire and modifying it to accept an f connector will be very time consuming and tedious custom job to do right.

On another note, my generator has a 12v outlet with angled tabs like this / \ . I have searched around and can't seem to find the plugs or even those same outlets anywhere. Does anyone know a source for these?

The problem with using their odd plugs and receptacles is that thrid oarty devices typically come with cig lighter type plugs for 12 use - cell phone charges come to mind.

So then you have to adapt the plug end of all these devices.

My cig plugs and receptacles are from Marinco (12V Plug & Receptacle | Marinco) and are very well engineered and attactive as well (alternative mouting options). The plugs have a FUSE in them which protects the wire and the device and the cover keeps water outand fingers safe.

Since I use some of the third party devices in the cockpit (Garmin Ique) AND in the car, AND down below, the cig lighter by Marinco is the best approach.

On the other hand for my solar panels I used twist lock because the wire diameter was too large for the cig plgs. I do remove them in winter and so forth.

Yes cigarette lighter plugs are ubiquitous, and conversion to Midget Locking Plugs gets very expensive as the number of portable 12VDC devices multiplies.

Nonetheless, the Midget Locking Devices are much better than even the very best Cig’ Lighter assemblies.

The Marinco "SeaLink” receptacle is about the same cost as the Midget Locking Receptacle; but of course you needn’t change out the portable equipment plugs (if you’re willing to accept the inferior quality of the OEM plugs); thus saving considerable expense. BTW: The Marinco is about the best (of a bad design concept) cigarette lighter receptacle.

In addition to the personal; satisfaction and utility “in use”, I had the added motivation (to install the “best”) of using my boat as something of a professional “demonstrator” (I was a marine electrician).

The Cig’ Lighter to Midget Locking adaptor was used for visitors’ equipment, and those devices that weren’t worth converting. Additionally I left the PO’s existing cig’ lighter receptacle installed.

As noted above, it’s my opinion that the Marinco “SeaLink” Cig’ Lighter devices are merely the best of a bad lot, and Midget Locking Devices are the very best solution I’ve found to portable 12VDC power. Of course, not everyone needs or wants the very best for the mundane uses typical of 12V receptacles; and for those, the Marinco product is an adequate (tho' not cheap) solution.

He said his cord got cut one day and he had to makeshift it and later decided if it works, why not keep it that way as there is no shortage of cable on a cable truck incase he cut it again.

I can think of several reasons, firstly that Oh so important missing third wire called the ground, Guess who becomes the ground when this rig fails as is highly likely and it won't be the wonderful voltage carring capabilities of RG-6 but it's amp delivery potential. Secondly, RG-6 (Radio Guide) wire center connductor is 18 guage, way too small for a 1/2" Hammer drill. Not to mention the resistance differences between a solid conductor and a wire woven as a signal shield. Do your buddy a favor and get him the right extension cord, you'll probably save his life.

Are you unaware of the some the factory 12 cig plugs? Have you looked at the wire size in some of these devices?

Using my Garmin IQue as an example, the OWM plug is well made and changing it to any other plug would be foolish. The wire sleeve (outer casing) mates perfectly with the plug and is held secure enough to pull the plug by pulling the cable. Though this is not advised, I doubt whether mini plug can clamp the many of cables (varying diameters) as well as. The same OEM quality is seen in most of the 12v portable devices I use. I don't what planet you are on Mr. Gord., but I on mine factory made up plugs are far superior to most of the after market hobbyist ones.

12v cig plugs, perhaps not the best inherent design are certainly workable for almost all portable 12 devices and changing to a "bastard system" system is not only expensive and time consuming, but accomplishes little for MOST portable devices.

I'd like to know which portable devices are you proposing be "re plugged"?

I suppose I could just use regular 120v outlets but to avoid confusion, I'd like it different.

Naw, Aqua, what you are avoiding is a boat fire. Someone other than you is gonna plug something 120vac into one of those one day and bad things could happen. As for your original question, which is something that DefJef cant seem to grasp, Gord has found a novel solution. If ya want to use a different 12v plug and socket, Gord's will work just fine. It's pretty obvious, since he's DONE it and LIVES with it daily. There's probably 40 more types you could use in the Digikey catalog alone. Whatever ya choose, leave a couple lighter sockets on the boat, or make up some adapters. Like Gord said, some stuff wont be worth converting.
